The Australian Geological Survey Organisation produced digital bathymetry, gravity, and magnetic grids for southwest Australia. The grids cover the region from 24 to 46 degrees South and 106 to 140 degrees East, integrating land, marine, and satellite data. The work was done in cooperation with Desmond Fitzgerald & Associates and the Australian Hydrographic Office.
Use Cases
- Modeling seafloor topography based on bathymetric grid data
- Analyzing subsurface geological structures based on gravity anomaly grids
- Mapping magnetic anomalies for mineral exploration based on magnetic grid data
- Integrating multi-source geophysical data for regional geological studies
Strengths
- Grids cover a defined geographic quadrant (24-46S, 106-140E)
- Data integrates multiple sources: land, marine, and satellite
- Collaborative production involving AGSO, Desmond Fitzgerald & Associates, and the Australian Hydrographic Office
Limitations
- Column-level documentation is absent; field semantics must be inferred after download
- Row count is unknown, which may limit suitability assessment
Provenance
- Source
- Australian Geological Survey Organisation (AGSO)
